  • How do I get videos to upload using ruby on rails carrierwave-video ?

    9 juillet 2016, par Eric

    Updated as of July 9, 2016

    I tried to follow the instructions on the github website for the video uploader process using carrierwave-video gem but get an error that says the file or directory mmpeg -i doesn’t exist.

    The upload path for images functions correctly, just not the video one.

    I have added all of the following code necessary to help solve the error and minified as much as i possibly could.

    Video uploader code using carrierwave

    class VideoUploader < CarrierWave::Uploader::Base

      include CarrierWave::Video
    
  storage :file
    

    
  version :mp4 do
    
    process :encode_video => [:mp4, resolution: "100x100"]
    
  end
    

    
  def store_dir
    
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    
  end
    
end

    Here is the movie controller code that handles uploading of videos

    class MoviesController &lt; ApplicationController
    
   include MoviesHelper
    

    
   def index
    
      mode "index"
    
   end
    

    
   def show
    
      mode "show"
    
   end
    

    
   def new
    
      mode "new"
    
   end
    

    
   def edit
    
      mode "edit"
    
   end
    

    
   def create
    
      mode "create"
    
   end
    

    
   def update
    
      mode "update"
    
   end
    

    
   def destroy
    
      mode "destroy"
    
   end
    

    
   def review
    
      mode "review"
    
   end
    

    
   def approve
    
      mode "approve"
    
   end
    

    
   def deny
    
      mode "deny"
    
   end
    
end

    Here is the model data for the movie that goes with it

    class Movie &lt; ActiveRecord::Base
    
  attr_accessible :created_on, :description, :maintenance, :reviewed, :subplaylist_id, :title, :user_id, :video, :remote_video_url
    
  belongs_to :user
    
  belongs_to :subplaylist
    
  mount_uploader :video, VideoUploader
    
end

    Here is where the movie is supposed to be displayed but it is not working

    &lt;% provide(:title, "Movie: Where movies are made!") %>
    
&lt;% provide(:keywords, "movies, video") %>
    
&lt;% provide(:description, "This is the place where users showcase their wonderful video talent.") %>
    
<p>&lt;%= notice %></p>
    
<h1 class="pageheader">&lt;%= @movie.title %></h1>
    
<br />
    
<p class="pagetext">&lt;%= video_tag(@movie.video_url.to_s, controls: true, class: "imagebox") %></p>

<br />
    
<p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @movie.subplaylist) %></p>

    Here is where the movie new action is

    &lt;% provide(:title, "Movie: Create new movies here!") %>
    
&lt;% provide(:description, "New movies are uploaded only to the site when the movie gets approved.") %>
    
<h1 class="pagetextheader">New movie</h1>
    
&lt;%= render 'form' %>
    
<p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @subplaylist) %></p>

    Here is where the movies forum parameters are

    &lt;%= form_for([@subplaylist, @movie], :html=>{:multipart => true}) do |f| %>
    
  &lt;% if @movie.errors.any? %>

      &lt;% @movie.errors.full_messages.each do |msg| %>
    
        <li>&lt;%= msg %></li>
    
      &lt;% end %>
    
      </ul>
    
    </div>
    
  &lt;% end %>
    
  <br />
    
  <div class="pagetext">
    
    &lt;%= f.label :title %><br />
    
    &lt;%= f.text_field :title %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.file_field :video %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.label :remote_video_url, "or video URL" %><br />
    
    &lt;%= f.text_field :remote_video_url %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.label :description %><br />
    
    &lt;%= f.text_area :description %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.submit %>
    
  </div>
    
  <br />
    
&lt;% end %>

  • "File doesn't exist" - streamio FFMPEG on screenshot after create method

    3 mai 2013, par dodgerogers747

    I have videos being directly uploaded to S3 using Amazon's CORS configuration. Videos are uploaded via a dedicated S3 form, once they have been uploaded successfully the URL of the video is appended to the @video.file hidden_field via javascript and then the video saves.

    I can't get this after_save method to work which takes a screenshot of the video and saves it to S3 via carrierwave after the video has been saved as a rails object. ( It was previously working using a carrierwave video upload instance )

    It errors out withErrno::ENOENT - No such file or directory - the file &#39;http://bucket-name.s3.amazonaws.com/uploads/video/file/secure-random-hex/video_name.m4v&#39; does not exist: I have tried running this method as a class method to call it from the console but it always comes back with the same error, even though the video exists.

    My bucket is set to public, read and write. How come it doesn't think the file exists ?

    If anyone needs more code just shout, thanks in advance.

  • Rails using stremio-ffmpeg gem to watermark a movie while uploading

    16 juin 2016, par Felix

    I am using carrierwave to upload a movie to amazon s3 that works perfect.

    Now I want to add a watermark to the movie while uploading or after uploading, I don’t know, what’s the best way ?

    I tried this :

    movie_controller.rb action uploadVideo

    movie = FFMPEG::Movie.new(@vid.video.url)
    

    
puts "........................................"
    
puts movie.inspect
    

    
if @vid.save

    Just to find out if the video is catched from stremio.

    But then I got the error that the movie is not found, the problem is that it doesn’t look in the amazon s3 bucket, it looks on my local server

    No such file or directory - the file '/uploads/tmp/1462954331-3471-8766/VID-20160424-WA0013.mp4' does not exist

    What could be the solution ? or should I do this in carrierwave uploader ?

    UPDATE :

    When I do this after the .save action it looks at amazon s3 bucket .. but also says that the movie isn’t there. But if I call it directly in browser it’s displayed.

    UPDATE Code :

    #Laedt ein Video hoch
    
def uploadMovie
    
  @user = User.find_by_id session[:user_id]
    
  #Holt alle Channels für die er eine Berechtigung hat (Eingeloggter user)
    
  @user = User.find_by_id session[:user_id]
    
  @knowledgeproviderList = @user.knowledgeprovider
    
  @channels = Channel.where(knowledgeprovider_id:     @knowledgeproviderList.pluck(:id))
    
  @vid = Movie.new(movies_params)
    
  @channel = Channel.find(params[:vid][:channel_id])
    
  @vid.channel = @channel
    

    
  #Fügt dem Movie einen Tag hinzu
    
  createTag params
    
  createCategory params
    

    

    

    
  if @vid.save

    Update error :

    Update :
    Added the code in the uploader :

      process :watermark_movie
    

    
     def watermark_movie
    
       if self.file.path
    
             options = {watermark: "images/header.png", resolution: "640x360", watermark_filter: { position: "RT", padding_x: 10, padding_y: 10 } }
    
             self.model.file = FFMPEG::Movie.new(self.file.path).transcode("#{root}/#{cache_dir}/#{self.cache_id}/file.mp4", options)
